Test::HTTP::LocalServer(3p)

NAME
Test::HTTP::LocalServer - spawn a local HTTP server for testing

SYNOPSIS
  use LWP::Simple qw(get);
  my $server = Test::HTTP::LocalServer->spawn;

  get $server->url, "Retrieve " . $server->url;

  $server->stop;

DESCRIPTION
This module implements a tiny web server suitable for running "live" tests of HTTP clients against it. It also takes care of cleaning %ENV from settings that influence the use of a local proxy etc.

Use this web server if you write an HTTP client and want to exercise its behaviour in your test suite without talking to the outside world.

METHODS

  "Test::HTTP::LocalServer->spawn %ARGS"
  my $server = Test::HTTP::LocalServer->spawn;

This spawns a new HTTP server. The server will stay running until
  $server->stop is called.

Valid arguments are :

•   "html =>" scalar containing the page to be served

•   "file =>" filename containing the page to be served

•   "debug => 1" to make the spawned server output debug information

•   "eval =>" string that will get evaluated per request in the server

    Try to avoid characters that are special to the shell, especially quotes. A good idea for a slow server would be

      eval => sleep+10

All served HTML will have the first %s replaced by the current location.

The following entries will be removed from %ENV:

    HTTP_PROXY
    http_proxy
    CGI_HTTP_PROXY

  "$server->port"
This returns the port of the current server. As new instances will most likely run under a different port, this is convenient if you need to compare results from two runs.

  "$server->url"
This returns the url where you can contact the server. This url is valid until the $server goes out of scope or you call
  $server->stop;

  "$server->stop"
This stops the server process by requesting a special url.

  "$server->kill"
This kills the server process via "kill". The log cannot be retrieved then.

  "$server->get_log"
This returns the output of the server process. This output will be a list of all requests made to the server concatenated together as a string.

  "$server->local"
  my $url = $server->local('foo.html');
  # file:///.../foo.html

Returns an URL for a local file which will be read and served by the webserver. The filename must be a relative filename relative to the location of the current program.

URLs implemented by the server

  arbitrary content "$server->content($html)"
  $server->content(<<'HTML');
      <script>alert("Hello World");</script>
  HTML

The URL will contain the HTML as supplied. This is convenient for supplying Javascript or special URL to your user agent.

  download "$server->download($name)"
This URL will send a file with a "Content-Disposition" header and indicate the suggested filename as passed in.

  302 redirect "$server->redirect($target)"
This URL will issue a redirect to $target. No special care is taken towards URL-decoding $target as not to complicate the server code. You need to be wary about issuing requests with escaped URL parameters.

  404 error "$server->error_notfound($target)"
This URL will response with status code 404.

  Timeout "$server->error_timeout($seconds)"
This URL will send a 599 error after $seconds seconds.

  Timeout+close "$server->error_close($seconds)"
This URL will send nothing and close the connection after $seconds seconds.

  Error in response content "$server->error_after_headers"
This URL will send headers for a successful response but will close the socket with an error after 2 blocks of 16 spaces have been sent.

  Chunked response "$server->chunked"
This URL will return 5 blocks of 16 spaces at a rate of one block per second in a chunked response.

  Surprisingly large bzip2 encoded response "$server->bzip2"
This URL will return a short HTTP response that expands to 16M body.

  Surprisingly large gzip encoded response "$server->gzip"
This URL will return a short HTTP response that expands to 16M body.

  Other URLs
All other URLs will echo back the cookies and query parameters.

EXPORT
None by default.
